I conducted the Academic Motivation Scale. This instrument returned three types of motivations, namely extrinsic, intrinsic and amotivation. The latter motivations means the absence of motivation towards cetain activity. In other words, no motivation. The descriptive analysis shows that mean of extrinsic motivation (M = 5.15, SD = 1.13) is higher than the mean of intrinsic motivation (M = 4.72, SD = 1.31). In this regard, my research question is "What is the statistically predominant type of motivation among graduate students to pursue master's degree?
Which test should I use to compare the means of these two motivation to examine possible difference? I quess that I could use paired sample t-test. However, from what I have read, this test compare means when the data collected in two times, before and after. In my case, I surveyed my sample at one time.
